Default Exhaust?

Who has done their own exhaust? what kind of tools are nessecary and what kind of budget high flow systems do you guys use/reccomend? I plan on tackling this after i move back home for the summer.



Thanks

Need to know what model you have. It makes a difference in your exhaust design. It'll differ for the SE, SSE/SLE, or SSEi.

Put that in your sig

My bonny is just a "bonneville" i have no markings for SE or otherwise. Everything about it indicates it is a 94, but has some wierd quirks that i gather came in in 1995 (odb2 connecter but odb1 codes) But its just a straight up series 1 3800. wish i had a supercharger, but i am happy just havin the bonny



thanks guys

2 1/4 fits just fine. Screw welding , spend 20.00 more and you can get the band clamp'* . They are stainless and cover the whole pipe.

I felt alot of diff with the dynomax. You can't hear a diff inside the car but ask someone to drive away and it sounds VERY NICE! Also improved milage. as far as the cat , I wouldn't spend my money on that. Depend on what your trying to do.
It should run anywhere from 100.00 to 200.00
I could do alot with 200.00.
plugs , wires , K&N , O2 and maybe coil packs.

I personally would say yes to the cat. You have an SE, so you have the simplest design. You don't have to worry about dual outlets while you shop for the muffler. The Dynomax is a great choice. The autosound cat is a good choice if you decide to do that, too. Just don't increase your exhaust diameter. It'* fine the way it is, and you won't lose backpressure if you leave it alone. I think Hector said something about a good price on the autosound....better than I paid locally.
